Steam injection is a widely used oil-recovery method that has been commercially successful
in many types of heavy-oil reservoirs, including the oil sands of Alberta, Canada. Steam is …

Steam injection is widely used for heavy oil and bitumen recovery. The advantage of this
process is its high recovery factor and its high oil production rate. However, the high …

Ultra-heavy oil resources have gained extensive attention due to their abundant reserves
and the shortage of conventional hydrocarbon resources. In this work, we investigate the …

The subcool or thermodynamic trap** for solvent applications is inefficient since solvent
viscosity is only a weak function of temperature. Another factor that affects the efficiency of …

Steam-Assisted gravity drainage (SAGD) technique has been successfully applied to unlock
the oilsands resources in Canada. But to accurately estimate the steam chamber expansion …

As a major technique for enhancing heavy-oil recovery, steam flooding has been used
successfully at large scales around the world. Long-term indoor experiments and field trials …

Abstract Steam Assisted Gravity Drainage (SAGD) is the most common technique for
bitumen extraction from oil sands. The main problems with SAGD and other conventional …

Coinjection of a low concentration of solvent with steam has been studied as an alternative
to steam-assisted gravity drainage (SAGD). This research presents a semi-analytical method …

Deeply-buried and high-bitumen-content crude oil is one of the most important energy
resources. Currently, Steam-and Solvent-Assisted Gravity Drainage (SSAGD) is an …

With increasing world demand for energy, greater attention has been given to the
exploitation of the huge resources present in the form of heavy oil and bitumen. Although …
